Lighting specifications sometimes aren’t worth the paper they’re written on; the lack of third-party validation means some brands/producers claim what they want, bending the figures to suit their own narrative. Nowhere is this more true than when it comes to lumen figures. In this article, we explain raw and actual/effective lumens, the difference between both, and the concept of 'Driver's FOV Flux' which we have applied in our calculations of effective lumens now published for our core product ranges.
